In the arrangement seen in Fig. 2, a third cylinder 21 is provided and the reciprocatory piston 22 therein, is connected by way of the connecting rod 23, with the main crank shaft 4. The lower face of the head 7 in this form of the invention has inclined side por-, tions disposed at right angles to the inclined termediate portions of the lower face of the head is horizontally disposed abovethe vertical cylinder 21 and in this manner the right angularly disposed abutment is provided for each cylinder.

aving open communication with the commonv com ression and explosion chamber 10. From t e foregoing description and drawings, it'will be seen that I have conceived, evolved, and produced a new type of multi- :51ple cylinder motor characterized by a greater compactness and convenience, in arrange ment ofparts, distinguished by simplicity andeconomy, and such in construction as to minimize resistance .in power transmissions, -to economize in fuel consumption, and to. bet ter fulfill the requirements of an engme of this class from a standpoint of efliciency in I -op eration.

It is believed that by considering the deof invention claimed may be resorted to in actual practice if desired.

Having thus described my invention, what I claim as new is z I An internal combustionengine of the character described comprising a motor block having a single compression and combustion chamber,'said block being further provided with intake and exhaust ports communicating with said chamber, a pair of inclined I cylinders communicating at their upper ends with the chamber, a vertically disposed cylinder intermediate the inclined cylinderscommunicating at its upper end with the scription in connection with the drawings, a clear understanding of the construction, op-.
